Abstract

In this paper, optical switch, optical filter and attenuator intensity system based on photonic crystal structure are investigated in terahertz frequency range for fast computing integrated system in communication and computer applications. A two-dimensional photonic crystal with triangular lattice structure is designed that consists of two bend waveguides with two point defects. In order to achieve a switch with high sensitive toward changing frequency, intensity of electric field in two waveguides at different frequencies and different sizes is compared for point defects. Simulation is obtained by using finite element method and finite-difference time-domain method.
